- From advisory:
"An attacker who has successfully authenticated to the Kerberos
administration daemon (kadmind) may be able to crash kadmind or induce
it to leak sensitive information, such as secret keys. For the attack
to succeed, it is believed that the configuration of the kadmind
installation must allow it to successfully allocate more than INT_MAX
bytes of memory."

- From advisory:
"A cryptographic weakness in version 4 of the Kerberos protocol allows
an attacker to use a chosen-plaintext attack to impersonate any
principal in a realm. Additional cryptographic weaknesses in the krb4
implementation included in the MIT krb5 distribution permit the use of
cut-and-paste attacks to fabricate krb4 tickets for unauthorized
client principals if triple-DES keys are used to key krb4 services.
These attacks can subvert a site's entire Kerberos authentication
infrastructure."

- From advisory:
"Buffer overrun and underrun problems exist in Kerberos principal name
handling in unusual cases, such as names with zero components, names
with one empty component, or host-based service principal names with
no host name component."
